Term
|
Definition

Term
|
Definition
| A population group with a shared characteristic |

Term

Definition
| live births / population x 1,000 (crude) |

Term
| Total fertility rate (TFR) |
|
Definition
| The average number of children that would be born to each woman if during her childbearing years she bore children at the current year's rate for women that age. |
|
|
Term
| Crude d.eath rate (CDR)/mortality rate |
|
Definition
| A mortality index usually calculated as the number of d.eaths per year per 1000 population. |
|
|
Term
|
Definition
| The number of children per woman that will supply just enough births to replace parents and compensate for early d.eaths, with no allowance for migration effects, usually calculated at between 2.1 and 2.5 children. |
|
|
Term
| Zero population growth (ZPG) |
|
Definition
| Population in equilibrium, stable. (plus immigration) |
|

Definition
Birth rate minus the d.eath rate
(cbr - cdr) |
|
|
Term
|
Definition
| The time period for any beginning total experiencing a compounding growth to double in size. |
|
|
Term
|
Definition
| A curve shaped like the letter J depicting exponential or geometric growth. (1, 2, 4, 8, 16...etc) |
|
|
Term
|
Definition
| A m.odel of the effect of economic development on population growth. A first state involves stable numbers with both high birth rates and rates, the second displays high birth rates, falling rates, and population increases. Stage 3 shows reduction in population growth as birth rates decline to the level of rates. The fourth and final stage again implies a population stable in size but with larger numbers than at the start of the transition process. An idealized summary of population history of industrializing Europe, its application to newly developing countries is questioned. |

|
|
Term
|
Definition

Term
|
Definition
| A statement of a population's future size, age, and s.ex composition based on the application of stated assumptions to current data. |
|
|
Term
|
Definition
| English economist, demographer, and cleric who suggested that unless self-control, war, or natural disaster checks population, it will inevitably increase faster than will the food supplies needed to sustain it. |

|
Term
|
Definition
| The advocacy of population control programs to preserve and improve general national prosperity and well-being. |
|
|
Term
| Population/demographic momentum |
|
Definition
| The tendency for population growth to continue despite family planning programs because of a relatively high concentration of people in the childbearing years. |
|
|
Term
| Demographic equation (specific m.odel) |
|
Definition
| P2 = p1 + B1-2 - D1-2 + IM1-2 - OM1-2, where P2 is population at time 2, p1 is population at beginning date, B1-2 is the number of births between times 1 and 2, D1-2 is the number of d.eaths during that period, IM1-2 is the number of in-migrants, and OM1-2 is the number of out-migrants between times 1 and 2. |
